Objective: To collect real-time LED data to a central site via a reliable Ethernet network. Recommended Products: Industrial Ethernet Switch (EDS-508), Serial Server (NPort 5610-16) Key Advantages: All LED data can be tracked through a redundant network with fast recovery. [b]Background:[/b] A local power distribution company provides electricity to nearly 40,000 commercial and residential customers, meaning nearly 80,000 people in the front of Colorado use this service. To anticipate potential anomalies across the industry, the company is constantly seeking new and unique ways to improve service quality and reliability for its customers at a low cost. To provide reliable power distribution services to more customers at a low cost, the company began expanding the local network subsystem of its power plants. A small SCADA system was used to integrate and control the power network, substations, and remote second substations onto an open platform. This small SCADA system required industrial-grade Ethernet switches with higher reliability compared to commercial switches, and a multi-port serial networking server capable of connecting and controlling all IEDs (Intelligent Power Devices) at each location. **Solution:** The company chose MOXA industrial Ethernet switches and MPort device networking servers because of their industrial-grade design, fast redundant ring network capability, ease of use, and low cost. The MOXA EDS-508 series switches feature a high-strength aluminum casing, IP30 protection rating, and an MTBF of up to 260,000 hours. MOXA's patented Turbo Ring technology provides reliable redundant ring network capability, recovering from network failures within 300ms, offering ultimate reliability for industrial communications. Furthermore, the device networking server's easy-to-use, multi-functional software simplifies and directly integrates communication equipment and LEDs during installation and configuration. Using the device networking server's COM MAP software, customers can easily map 256 COM ports, connecting LEDs in seconds. **Advantages:** • Fast ring network recovery effectively reduces downtime losses. • COM mapping software expands remote control capabilities. • High MTBF and long-term quality warranty enhance system reliability. • Easy-to-use software reduces technical support costs. • A streamlined management platform reduces maintenance costs.
